Right. You would generally need two IR triggering devices to sense entry from both directions so reach deep into your wallet unless you roll-your-own.
To your point, some accessories can indeed be tricky to wire-up to two IR devices because they can "conflict" - that is, one trigger saying "occupied" and the other trigger saying "unoccupied".
